6 Claims. (01. 105270) My invention relates to improvements indumpbodies for vehicles wherein a pivotally mounted body has an inclinedbottom to produce a greater capacity upon one side of its pivotal axisthan the capacity upon the opposite side thereof, said lesser capacityside being weighted and heavier than the greater capacity side only whensaid body is unloaded, said body operating in conjunction with a seriesof connected latches arranged to engage said body and prevent movementthereof from and to loading and dumping positions, whereby said body maybe moved, when loaded or unloaded, from, and to, said dumping andloading positions respectively, by the attraction of gravity when saidlatches are released.

The primary object of the present invention is to provide a new andimproved dump-body.

Another object of the invention is to provide a new and improveddump-body having improved means for automatically moving said body toand from loading and dumping positions, as may be required.

A further object is to provide a new and improved device of thecharacter set forth having improved means for automatically moving adump-body from loading to dumping position and from dumping to loadingposition.

A still further object is to provide new and improved means forretaining a dump-body in either loading or dumping position, and forreleasing said body from either position.

A still further object is to provide a single element, which, whenactuated, will release said body from either position.

A still further object is to provide a new and improved dump-body which,will normally be pivotally supported in an unbalanced state to move saidbody to a dumping position when loaded, and to move said body to aloading position when unloaded.

I accomplish these and other objects by means of the improved devicedisclosed in the drawings forming a part of the present application,wherein like characters of reference are used to designate similar partsthruout the specification and drawings, and in which- Fig. 1 is a partlybroken end elevation of my improved dumping-body mounted upon a vehicle;

Fig. 2 is a side elevation thereof; and

Fig. 3 is a partly broken plan view of the device.

Referring to the drawings the numeral 2 is used to designate in generala suitable supporting frame mounted upon a suitable vehicle I, which maybe a rail-car, as illustrated, or any other suitable vehicle adapted fortransportation.

Pivotally mounted upon the frame 2 is a body 3 having an inclined bottom4, which bottom 4 is inclined transversely thru the longitudinal axis ofthe pivotal support 6 of said body 3, as disclosed in Fig. 1 of thedrawings, whereby the body 3 has a greater capacity upon one side of itspivotal support 6 than the capacity of said body 3 upon the oppositeside of said pivotal support 6, whereby said greater capacity side ofsaid body 3, when loaded, will be actuated by the attraction of gravityto move the said body 3 to a dumping position in a manner hereinaftermore fully set forth.

The lesser capacity side of the body 3 is provided with a suitableweight 1, while a second weight 8 depends from the body 3 and directlyunder its pivotal support 6, the weight of said combined weights and theweight of a load in the lesser capacity side of said body 3 being lessthan the weight of a load in the greater capacity side of said body 3when said body 3 is loaded.

The side of the body 3 adjacent, or on, the greater capacity side isopen and a door 9 is hingedly suspended from the body 3 and is actuatedby the attraction of gravity to close said side when the body 3 is in aloading position, and to normally open said side when said body 3 is ina dumping position, as disclosed in dotted lines in Fig. 1 of thedrawings.

Rotatably mounted within the frames 2 on each end of the vehicle I aretransverse shafts ll, each being provided with a series of latches l2,l3 and I4, rigidly connected to their respective shafts H, and engaging,respectively, stops l5 and I6, mounted upon the ends of the body 3, andcatches ll projecting from the bottom of the door 9, said series oflatches I 2, l3 and I4 being thus connected so that the body 3 may bereleased from either dumping or loading position in a manner hereinaftermore fully set forth.

Each shaft II is provided with a depending lever or arm l8 to which areconnected rods 2| passing thru suitable supports 22. A spring 23 isinterposed upon each rod 2| and between said levers l8 and the supports22, as disclosed in Figs. 2 and 3 of the drawings.

Links 24 connect said rods 2| to opposite sides of the pivot 26 of anoperating or releasing lever 21 whereby one movement of said lever 2'!will actuate the shafts I l and move all of the latches I2, i3 and M todisengage their respective stops l5 and 16 upon the body 3 and thecatches I! of the swinging door 9, and against the tension of thesprings 23, which tension will tend to normally retain engagement of thelatches with their respective stops.

The body 3 is held in horizontal or loading position by means of asuitable longitudinally disposed support or angle iron 28 secured to theframes 2 and under the lesser capacity side of the body 3.

In operation when the body 3 is loaded, the greater capacity side, orthat side adjacent the open side or door 9, is the heavier.

When the operating lever 21 is moved to pull the rods 2I against thetension of the springs 23, the levers I8 partially rotate or oscillatethe shafts I I and the latches I3 and I 4 are disengaged from theirrespective stops IS and catches H on opposite ends of the body 3, andthe attraction of gravity, acting upon the load of greater capacity onthat side of said body 3, will lower the said body 3 to dumpingposition, as disclosed in dotted lines in Fig. l of the drawings, and,the catches I I being released, the door 9 will swing open by gravityand the load will slide from the inclined bottom 4 thru the open end ofthe body 3 and be discharged.

When the body 3 moves to such position, the stops I5 on opposite ends ofsaid body 3 will be moved into a position where they are readily engagedby the latches I2, and said body will thus be held, or retained, indumping position by said latches I2, so that any lodged or unloadedmatter may be liberated and removed, or permitted to slide down theinclined bottom 4.

After the load has been duly discharged or dumped, the operating lever21 is again operated, which will oscillate the shafts II, ashereinbefore described, against the tension of the springs 23, andrelease the latches I2 from engaging relation with their respectivestops I5, and, the now heavier side of lesser capacity (upon which theweight 'I is attached), will, operating in conjunction with thedepending weight 8, be actuated by the attraction of gravity and thebody 3 will be automatically moved to a loading position and supportedupon the longitudinal support or angleiron 28, as disclosed in fulllines in Fig. 1 of the drawings.

As the door swings closed, the catches I1 thereon, being provided withbeveled ends II, will move between the latches I4 and the ends of thebody 3 and move said latches I 4 outwardly to permit the passage of saidcatches I'I beyond said latches I4 and thereby permit said latches I4 todrop back into securing position.
